Well, when it comes to communication protocols, there are some facts: 1. Ethernet is completely different from USB: Ethernet is an asynchronous, bandwith-sharing, LAN protocol. USB is a serial, point-to-point protocol. Two different things. The only thing they have in common, is that they both send and receive data.
2. Ethernet has error detection, collision detection and error correction. An invalid or lost frame is resend by the sender. Fortunately. 3. Synchronous USB (the one used for file transfer, for instance) has error detection, and error correction : an invalid or lost packet is discarded by the receiver. The receiver requests the re-sending of lost or invalid packets. 4. Isochronous USB (the one used for audio/video) has error detection, but no error correction : an invalid or lost packet is discarded by the receiver. With isochronous data it is not possible to retry a failed transaction. There is no handshake packet (as such a packet would cause transmission delay and time upsetting of the data delivery) and the data must be accepted "as is". 5. There's nothing defined in the protocols about the cable color : you can paint it gold. :) -- Themis SB3 - North Star dac 192 - Denon 3808 - Sonus Faber Grand Piano Domus ------------------------------------------------------------------------ Themis's Profile: http://forums.slimdevices.com/member.php?userid=14700 View this thread: http://forums.slimdevices.com/showthread.php?t=66445 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
